IMPROVEMENT IN ROTARY HARROWS.

Specifica-tion forming part of Letters Patent No. 24,554, dated June 2S, 1859.

To all whom it may concern:

Be it known that we, CHRISTIAN GINGEICH and JOSEPH K. GINGRICH, both of Annville, in the county of Lebanon and Slate of Pennsylvania, have invented a new and useful Improvement in Rotating Harrows; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, of which- Figure l shows a plan view of the harrow. Fig. 2 is a side view of the same. Fig. 3 is an enlarged view, showing in section the manner of connecting the parts to the center ot' the barrow.

The nature of our invention consists in arranging clearers upon the weighted arm of a rotating barrow so as to precede the traveler or friction-roller, which supports the weight, and keep the annular ring upon which the traveler rolls clear of dirt in using the barrow.

A represents a common circular harrowframe, armed with teeth in the usual manner, and B the circular ring, secured by bolts to the frame A.

G is a weighted arm, pivoted to the center of the harrow,andon the end of which is abox, D, for receiving the Weights.

.E is a shaft, also pivoted to the centerof the barrow below the arm C. A bar or draft-pole, F, is attached to this, near the center of motion ofthe barrow, which extends out to the eX- trelnity ofthe shaft E, and has a slot in it into which passes a curved plate, a, which is xed to the end of the shaft E. This, being perforated, receives a pin, b, which holds the pole F rigidly in any position desired upon the plate,

so as to change the line of draft of the team and preserve a level draft to the barrow. To the end of this bar a crook is formed for attaching the team to the harrow.

Gr is a traveler or friction-roller, which supports the end of the arm C, carrying the weight, and travels upon the ring B as the harrow is drawn forward and revolved. From either side of the arm C are bent plates H H, one of which precedes the friction-roller G in either direction of the harrow. These plates come near the surface of the ringBand keepit clear of dirt, tc., which would materially hinder the turning of the barrow.

The shaft and weighted arm are pivoted to the shaft J in the center of the barrow, which passes through the barrow-frame and receives a nut upon its lower end, which holds the shaft firmly in position. The portion J of the shaft is enlarged, forming a shoulder which rests upon a plate, c, fixed to the barrow by bolts. Upon this plate rests a similar plate, e, fixed to the shaft E, and having a collar, j', around which the shaft E and arm C turn. The whole are then secured together by a nut, g, and the arm and shaft are fixed at right angles to each other by a connecting-bar, h, and the harrow is ready for operation.

What we claim as new, and desire to secure by Letters Patent, is-

The clearers H, in combination with roller G and ring B, when arranged substantially as and for the purposes herein set forth.
